' This invention relates to a han'dlever operated vise and it consists in the novel'features hereinafter described and claimed.

An object of the invention'is to provide a vise structure of the character stated which i may be applied-to a bench .or other support and which may be easily and quicklyoper ated by manipulating a lever mechanism whereby articles or materials may be secure ly held in position while they are being worked upon. I With this and other objects in-viewthe structure includes a standard having means at its upper end for supporting a vise jaw and means provided at its lower end where by the standard may be secured to or ,mounted upon a 11001- other support. A bracket is connected with the intermediate portion of the standard and may be attached to a bench or other suppo'rtjAn arm is pivotally connected with the lower'portion of the standard and carries at its free end a jaw member adapted to coact with the first as at 6 and the exterior surface thereof is =provided'with ridges 7. A block Sis m vided"at its'side edge with a recess 9 which 'receive'sthe side portion of the tapered end mentioned ,jaw. Links are pivotally connected together at their inner ends" and the outer ends of the links are pivotally connected with the intermediate portions of the standard' and the arm, respectively. One g to rest upon the upper surface of afloo'r or other support (not shown). .A bar 10 is atofthe links is provided with longitudinally disposed slots. A diskis'pivoted'upon the intermediate portion of the; arm and carries 'a pin which-is adapted to move along'the slots of that link provided with the same.

A lever is pivoted upon theaxis of the disk 7 V i g of the block 8 and'a cam lever 12 is pivoted 'uponthe said plate 11. The cam end of the I? I and is providedwith apawl adapted to move between. teeth provided at the periphery ofthe, diskuand which may be used as means for swinging the disk in order to move the links with relation to each other,

whereby the arm is swung with relation to the standard. "A spring actuated pawl is carried by the arm, and is adapted to engage the teeth of the disk; whereby thedisk may be heldatan adjusted position) In the accompanying drawings z- Figure 1 is a side elevational view of the parts shown in section.

" The vise structure include'sa standard 1 which is provided at its upper end with a socket 2 leading in'from the side thereof. A

jaw 3 is provided with a shank 4L whichfits snugly in the socket 2 whereby the said jaw held at the side of the standard 1. The 7 "face of the jaw 3 is provided with grooves or serrations 5 adapted to' hold the workfor material such as pipe, plankyorother 'fart cl'es whlch are to be out or worked upon.

The'lower end of thestandard 1 is tapered 6 of the standard 1. The block 8 is adapted 1 tached to the edge of. the block8 and may be 'A plate 11 is mounted at the outer edge lever 12 bears against a block 13'whioh is gslidably mounted between the plate ll-an'd the body portion of the block 8. i The block 13 is provided with arecess '14 which bears against the ridges 7 of the standa'rd 1. The block 13 is provided with pins 15 whlch are received in bores 16 1)rovided in the block .8 andsprings 17 are interposed between the blocks '8 and. 13 and serve as means, having a tendency, to move the block 13 in a position away from the block 8 whereby the standard 1 may be released from between the blocks when the lever .12 is 'moved to a positionso thatv the narrower portion of its cam end is interposed between the fulcrum of the lever to. the block 13.

Bracket sections 18 are provided with openings 19 adapted to receive bolts 20 whereby the said sections may be secured to a bench'o r other support (not shown). The h sections 18' are secured together a bolt 21 which passes transversely through the said sections. The said sections areprov1ded with recesses 22 which receives the intermediate portion of the standard 1' and by tightening the nut upon the bolt 21, the

said standard 1 is clamped between the bracket sectionslS andsuch'means areprovided to securely hold the standard ,1 in a fixed-position with relation to its support-- ing means. v

Links 23, and 24. are pivotally connected together at their inner ends. The link 24 is i longer than the link 23. The other ends of the links 23- and 24' are pivotally' connected .With the standard 1 and an arm 25 which in turn is pivotally connected with the lower portion of the standard 1. Ajaw 26 is car- .ried. at the upper free end of the arm 25 and is adapted to co operatewit-lithe jaw member hereinhefore explained and referred to. A. disk rne mber 27 is. pivoted upon the arm' 25 and; carriesa pin '28" whichis slidahly received in slots 29' provided inrthe intermediiate portion the link 24; The disk 27 *is'provided atfitskedge with teeth 30 and 31; A 3 lever' 32"i-s tulcrumed upon the axis of the disk 27 and a hand grip member a 33 is; pivoted upon the-lever. A spring '34 is interposed between thelfree end portion re-i the lever 32 and grip 33 and serves as meansfor normally holding, the grip in a a "spread; position: with relation to: the lever.

v as

A pawl run, 35 is connected atone end with the'grip: 33 and its other-lend is adaptedto engage-min the spaces between the'teeth 30 whereby the lever 32 may he held and secured, in a fixed position with relation to the dfisk27. A pawl36 is-pivoted upon: the arm 25, audits free end is adapted to enga'ge'the teeth 31.01 the: disk v2'2 whereby the "said disk'may be held at a fixed position 7 v with relation to the arm 25. A spring' 36V "pawl 3'6.

A is interposed between the arm 25' and? the 45 pawl 36 and serves as means for holding the free end of the pawl in engagement with the -teeth31' as best sh'own in: Figure 1 of the 'jdrawin'g. uponthe arma25- and the cam face of the lies against the edge. of the A 10am faced disk 37 is pivoted said disk 37 1 By turning the disk 37' upon the arm 25 the pawl 36 may be swung to a position,

'1 against thetension of the spring 36 where- 'by'the free end of the pawl is held beyond 7' the path of movement ot-the teeth 31 and when: in such position the disk 27r is released and ,is ready tobe swung by manipulating the." lever '32 and with relation to the arm 25. The free end o f'the arm 25 is provided with grooves 38 which are adapted to re ceivethe shank 39 of the jaw member 26.

As shownin, Figure 9,: a jaw member 40 havi-n-g a plane surface may be provided,

and used in lieu ofthe jaw member While the other ends of the said links come toward each other, the arm 25 is swung toward the standard land the jaw member 26, clamps against the outer surface of the article which has been placed against the jaw member 3. 33 and moving the pawl rod 35 the parts;

By manipulating the'grip are moved so that the article may he held turned; so that the tree'end the pawl 36, under the influence of the spring 36 en-.

tightly between the jaws'ofthe vise. Then V .the article is clamped the dislpme'mher37i is a gages the teeth 31 and. thus the article is secured iii-position between the jaws, In order to remove the article from between: the jaws of the device, theopera-tion, above described, is reversed.

' Therefore, itwill be seen that a vise structure of'sim'ple and durable arrangement of parts is provided and that" the same: may

be easily and'quickly' manipulated for secur- V i-ng and holding an article in a stationary position and that the parts may be easily and quickly manipulated for releasing and removing the article. from the vise structure.
